Sewing Machine Repair Resources Page

As a sewing machine repairer, I notice that the need for more repairers is increasing. I tend to say that "we are a dying breed", which is a real shame. With this page, I want to contribute to more people being able to repair sewing machines. As the workload is now, I unfortunately do not have the opportunity to answer questions related to this page or specific repair matters.

Electronic Schematics - Service Manuals - Parts

These are technical drawings I have made by studying PCBs I have access to. Not all electronic components have been possible to specify with a type designation, while others are no longer produced. In those cases where I have found replacement components, I have noted which they are. These are my own drawings and notes that I use when troubleshooting in my daily work as a sewing machine repairer, and may contain errors and component variations from the machine you may have on your workbench. Since this is my own material, I of course take no responsibility for any mistakes or problems that may arise, but I hope you can be helped by what I share. If you find errors, have additional information, or have suggestions for changes, it would be nice if you let me know.

Support

As much as I enjoy working on this, it takes a lot of time. I wish I could take more time to complete the online course on repairing sewing machines, but time must be prioritized. If you want to support the work I am doing and help me finish these courses faster, you can do it here: patreon.com/sewrepair
